I was on Lexapro 20mg for a few years but it pooped out, I suggested Prozac because I had a lot success on it in my mid 20's. The transition has been horrible. 3 weeks into the Prozac and I am having body sensations, and heart palpitations. I wore a heart monitor for 24 hours, and cardiologist said my heart is fine, no issues... so why is it happening? My heart skips a beat once in a while, My cardiologist said don't worry about it. Seeing the shrink tomorrow to see about changing or adjusting meds. I have been afraid ever since I started this Prozac. Only 10mg. So if my heart is good then its the Prozac right?
